Galvanized steel is protected against rust by a surface coating that insulates it from air, water, etc. In normal environments, galvanized steel with a high zinc coating has a lifespan of 20–50 years. However, surface rusting often occurs due to humid storage environments, thin zinc coatings, etc. Effective surface preparation and preventive measures are essential. […]

PPGI, Pre-Painted Galvanized Iron, and PPGL are color-coated steels made from cold-rolled or galvanized steel substrates coated with organic paints. They are widely used in the construction and manufacturing industries for their aesthetics, rust resistance, and workability. Wanzhi Steel has provided many solutions to appliance manufacturers and roof and wall fabricators in over 100 countries.
